(Optional) Installing the IB driver

Scenario

CentOS 7.4 is used as an example.

1. The IB driver can be installed only for CentOS 7.3, CentOS 7.4, CentOS 7.6 ARM, RedHat 7.3, RedHat 7.4, SUSE 12 SP3 and Oracle Linux 7.4.
2. You are advised to install the 4.2 or later version.

Prerequisites

• You have logged in to the VM.
• The required IB driver installation package has been uploaded to the VM.

Procedure

1. Download the OFED package as instructed in Software.

   Download the .tgz installation package based on the VM OS and verify the file integrity.

   Take CentOS 7.4 as an example.

   

2. Upload the downloaded OFED installation package to the VM. For details, see Configuring the VM Environment.
3. Run the tar -zxvf xxx command (xxx indicates the OFED installation package name) to decompress the package.
4. After the decompression is complete, go to the MLNX_OFED_LINUX-4.2-1.2.0.0-RHEL7.4-X86_64 folder to install the package.

   ./mlnxofedinstall

   [root@localhost MLNX_OFED_LINUX-4.2-1.2.0.0-rhel7.4-x86_64]# ./mlnxofedinstall
